  3. Chapter Objectives • Describe the phases or stages in systems engineering and the new product development process • Recognize product liability and safety issues • Recognize the significance of reliability and other design factors

  4. New Product Development • Approval to expend resources and agreement on work to be done • Accomplishment of work on stage • Complete results • Proposed plan for next stage • Review – formal or informal

  5. Engineering Problem Solving Approach • Define the problem • Collect and analyze the data • Search for solutions • Evaluate alternatives • Select solution and evaluate the impact

  6. Exhibit 1: Typical Product Life Cycle

  7. New Product Development Stages • Conceptual • Technical Feasibility or Concept Definition • Development • Commercial Validation • Production • Product Support • Disposal Stage

  8. Concurrent Engineering Set of methods, techniques, and practices, that: • Consideration within design phase of factors from later in cycle • Produce design of processes • Facilitate reduction of time required to translate design into products • User ability to meet user’s needs

  9. Engineers Must Communicate • Drawings • Specifications • Financial Estimates • Written Reports • Oral Presentations • Sales

  10. Control Systems in Design • Drawing Release • Configuration Management • Design Review Board

  11. Special Considerations in Design • Product liability • Safety • Reliability • Maintainability • Availability • Ergonomics • Producibility

  12. Liability • Designer foresee unlikely conditions • Product contains adequate warnings • Risks reduced to greatest extent possible • Meets user’s reasonable expectations of safety

  13. Safety Safeguards to Reduce or Eliminate Accidents Influenced By: • Design • Proven materials and components • Proven manufacturing methods • Clear instruction

  14. Reliability • Probability that the product will perform a specified function • Under specified conditions • For a stated period of time

  15. Maintainability • Administrative and preparation time • Logistics time • Active maintenance time

  16. Ergonomics • Human Factors engineering • Science of designing machines, products, and systems to maximize the safety, comfort, and efficiency of the people who use them

  17. Ergonomics • One of primary goals is prevention of workplace illness and accidents • Use simulations – replicas of workstations, aircraft, cars, trucks ….

  18. Value Engineering • What is it? • What does it do? • What does it cost? • What is it worth? • What else might do the job? • What do alternatives cost?
